Document Type and Number:
Japanese Patent JP6721430
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a woundable sheet while having high rigidity in one direction.SOLUTION: A sheet 1 has a first main surface 1a and a second main surface 1b having a plurality of linear projections 2 extending in one direction. A first resin-impregnated fiber sheet 11 constitutes the first main surface 1a. A second resin-impregnated fiber sheet 12 constitutes the second main surface 1b. A resin composition layer 13 fills a space between the first resin-impregnated fiber sheet 11 and the second resin-impregnated fiber sheet 12. The plurality of linear projections 2 are provided at spaces from one another in the other direction different from one direction. When a thickness in a portion positioned between the adjacent linear projections 2 is represented by t, expression t≤0.6 holds.SELECTED DRAWING: Figure 1
